Refrigerator condenser and refrigerator

Abstract

The invention discloses a refrigerator condenser which comprises a condensation pipe and refrigerants flowing in the condensation pipe. The refrigerator condenser further comprises a closed heat exchange belt, and heat exchange working media are arranged in the heat exchange belt. The heat exchange belt abuts part of or the whole condensation pipe in parallel so that heat exchange is performed on the heat exchange working media in the heat exchange belt and the refrigerants in the condensation pipe. According to the refrigerator condenser, the characteristic that the specific heat ratio of water is larger than that of air is utilized, the heat exchange efficiency of the condenser is improved by adding the heat exchange belt, the energy-saving effect is obvious, and the complete refrigerator can save energy by more than 20 percent.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a refrigerator condenser and a refrigerator using the refrigerator condenser. Background technique [0002] In the prior art, the refrigeration circuit of a refrigerator generally includes four major components: a compressor, a condenser, a capillary tube, and an evaporator. The high-efficiency refrigeration function of a refrigerator requires a perfect match between the compressor and the refrigeration system. People often focus on the structural layout and design of the evaporator. In order to improve the cooling efficiency of the system, the optimization of the condenser is often ignored. Since the refrigerant in the condenser tube is a two-phase mixture, its pressure reflects the outlet pressure of the compressor, and the work of the compressor follows the exhaust gas. Therefore, the heat dissipation characteristics of the condenser have a great influence on the entire ...

Problems solved by technology

[0003] In the traditional refrigerator design, the condenser is initially hung on the back of the refrigerator, but for the sake of beautiful appearance, the condenser is gradually developed to be pasted on the inside of the side panel of the refrigerator, and the external and built-in condensers, the condenser tube The heat of the refrigerant is released into the air through the heat exchanger. Since the condenser tube is a round tube, the contact area between the coil-type built-in condenser and the side plate of the refrigerator is small, and the heat exchange area needs to be increased to To make up for its inherent defects, and the external type of condensation mostly uses welding steel wires on the condenser tube to increase the heat transfer area, and there is also a situation where the heat transfer efficiency is not ideal
